this is the PSU I was talking about. Its box and wiring still needs to be completed.
The two big holes are for these connectors.
One of these connectors will carry the energy to a power distribution box, where I will install six Mini-Fit Jr connectors, and each Mini-Fit Jr connector will have its dedicated wire for a load.
The max current is between 1.1A and 1.5A.
The total current provided by the PSU is 5A (the sum of all the loads' currents).
The min current in the lightes load is 100mA.
They are "light loads" when compared to a modern computer, where a single wire can carry more than 5A.
